The pier column is formed into a single-box single-chamber cross section by four-limb lattice columns and concrete rib plates among the columns, each lattice column is composed of a steel pipe with a diameter and concrete with the thickness of 20cm coated outside, and the wall thickness of the concrete rib plates among the lattice columns is 50 cm. The steel pipe is internally provided with C80 self-compacting compensation shrinkage concrete, and the rest parts are C30 self-compacting compensation shrinkage concrete. Vertical every 12m sets up the cross slab that a 1m is thick in the mound, and the length that divides the segmentation of lattice mound steel pipe is corresponding with the baffle interval. And a flat supporting beam and an inclined supporting beam are arranged between the steel pipes, only the flat supporting beam is arranged along the bridge direction, and the steel pipes are connected with the flat supporting beam by bolts and welded with the inclined supporting beam.
Construction difficulty: firstly, the single steel pipe of the lattice column of the main bridge has large hoisting weight and high hoisting height; secondly, the single steel pipe is long in overhead positioning and splicing operation time and high in safety risk; thirdly, the difficulty of pumping concrete in an ultrahigh and long distance is high, fourthly, a main pier is constructed by adopting a conventional large tower crane, the installation of a steel pipe and the construction of concrete wrapping the pier column are mutually interfered, and the construction period is long; fifthly, the cantilever of the convex diaphragm plate of the main pier is long, and the climbing difficulty of the template is high; sixthly, the requirement on the performance of the C80 high-throwing self-compacting compensation shrinkage concrete on the mixing ratio is high.
In order to solve the problem that the installation of a steel pipe for hoisting a main pier and the construction of the outer concrete of the pier stud interfere with each other when the main pier is constructed by the conventional tower crane, the utility model discloses a special development of a combined type lifting tower crane on a self-climbing type heavy lifting machine is based on another invention 'a self-climbing type heavy lifting machine' (simultaneously applied for another case).
